Does www-data have write permissions in the CoreDumpDirectory? Another method to set the core dump directory in linux is echo "/var/tmp/core-%e.%p" > /proc/sys/kernel/core_pattern The ulimit is only valid for the shell (and subsequent child processes) you're currently in, so you should restart apache from the same shell. You can test if your configuration works by just sending a SIGSEGV yourself, just kill -11 one of the apache processes. rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org
